This creamy, cheesy, and slightly sweet corn casserole comes together in under 45 minutes with simple pantry staples. Perfect for potlucks, holiday dinners, or a comforting weeknight side dish.
Don’t overmix the batter to avoid a dense texture. Let ingredients come to room temperature for best results. For a spicier version, add diced jalapeños and use pepper jack cheese. For a gluten-free option, use a gluten-free corn muffin mix. Leftovers keep in the refrigerator for up to 4 days and freeze well for up to 3 months.
